使用Mocha、Chai、node.js测试异步方法

// asyncFunction.js
module.exports = {
  async asyncMethod() {
    return new Promise((resolve) => {
      setTimeout(() => {
        resolve('Hello, World!');
      }, 1000);
    });
  },
};

npm install mocha chai

// test/asyncFunction.test.js
const { expect } = require('chai');
const asyncFunction = require('../asyncFunction');

describe('asyncFunction', () => {
  it('should return "Hello, World!"', async () => {
    const result = await asyncFunction.asyncMethod();
    expect(result).to.equal('Hello, World!');
  });
});

npx mocha test/asyncFunction.test.js
